SHOCK-GRAPPLE.

To all whom it may concern.-

Be it known that I, JAMEs B. SoHUMAN, a citizen of the United States,residing at Indianapolis, in the county of Marion and State of Indiana,have invented certain new and useful Improvements in Shock-Grapples, ofwhich the following is a specification.

The obj ect of my invention is to provide asimple but effective meansfor tightly embracing a shock of cornor the like by means .of which theshock may be lifted bodily, the

arrangement being such that the grapple;

The effective length of the two strap mem -bers and 10 may be varied bymeans of a hook 12, carried by the member 10 and adapted to enter anyone of a series of holes 13, formed in the member 10. The free end ofthe member 10 carries a clip 14, into which is detachably hooked apulley-block 15. The free end of themernber 10 is similarly providedwith a clip 16, to which is attached a pulley-block 17 4 A cable 18 hasone end secured to the block 17, and the other end passes around thepulley-block 16 and from thence around the pulley-block 17.

Each of the strap members 10 and 10 carries a plurality ofinwardly-projecting prongs 19, which are adapted to enter a shocktransversely, and thus prevent the strap membersfrom slippinglongitudinally of the shock.

In order to permit the easy withdrawal of the grapple, especially if theshock be laid down,as. it is deposited, I prefer to mount each of theprongs '19 upon a rock-shaft 20, which is pivoted in a suitable bracket21, which is attached to either member 10 or 10. The shaft 20 isprovided with a central notch 21, in which lies the free end of a s ring22, the arrangement being such that t e s ring normally holds the prongsat right ang es to Specification of Letters Patent; Application filedApril 20, 1905.

the strap members, but permitting said prongs to be swung downward ineither direction parallel with the strap members, as indicated in dottedlines in Fig. 2. I

In operation the block 15 is linhooked from the clip 14 and the strapmembers are caused to embrace a shock, the prongs 19 entering the shocktransversely. Block 15 is then rehooked into the clip 14, and by pullingupon cable 18 the grapple may be tightened about the shock, and when ithas become sufficiently tightened further ull upon the cable-will serveto lift the shoc bodily. If'the shock be laid down as it is deposited,

the operator maynevertheless easily remove the grapple by unhooking theblock 15 and pulling t e grapple lengthwise from beneath the shock, theprongs 19 yielding to one of The ength of the grapple may be readilyadjusted by shifting the hook 12 from one to the other of theperforations 13.

I claim as my invention- 1. A shock-grapple comprising a flexiblemember, means for drawing the ends of said the positions shown in dottedlines in Fig. 2.

member together, and prongs mounted upon saidmember to project from oneface thereof.

2. A shock-grapple comprising a flexible member, means for drawing theends of said member together, and prongs yieldably mounted uponsaid/member to normally project from one face thereof.

3. A shock-grapple consisting of a-flexible member, and prongs mountedupon the inner face thereof, each of said prongs being pivotallysupported upon an axis substantially parallel with the face of theflexible member.

4. A shock-grapple consisting of a flexible member, and prongs mountedupon the inner face thereof, each of said prongs being'pivotallysupported upon an axis substantially parallel with the face of theflexible member, and a spring for normally holding said prongs in aprojected position.

In witness whereof I have hereunto set my hand and seal, atIndianapolis, Indiana, this 12th day of April, A. D. 1905.
